River dynamics and sediment transport play an important role in river bed morphology.
Building a bridge pier along the river alters the cross‐section of the river and causes the …

In this work experimental and numerical investigations were carried out to study the
influence of the geometric parameters of trapezoidal–triangular labyrinth weirs (TTLW) on …

ABSTRACT Computational Fluid Dynamics (CFD) represents a useful tool to study natural
currents in the rivers and estuaries with erosive materials; therefore, it is always in the keen …

Piano Key (PK) and trapezoidal labyrinth (TL) weirs are nonlinear control structures suitable
for narrow channels with high discharge by expanding the crest length of the overflow. In …

The present study deals with numerical simulations of the free and submerged hydraulic
jumps over different shapes of roughness in various roughness arrangements and different …

Side weirs are important structural measures extensively used, for instance, for regulating
water levels in rivers and canals. If the length of the opening is limited, the amount of water …

In this study, the effect of the presence of bed-block roughness in an ogee spillway on
energy dissipation and jet length is investigated. A series of experimental and numerical …

The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow,
specified by strong turbulence, air entrainment and energy loss. Despite recent studies …

ABSTRACT Piano Key Weir (PKW) is a non-linear weir with a small foundation footprint that
allows large discharges through a narrow channel. The presence of overhangs classifies it …

Finding an optimal design for hydraulic structures and devices, which work together in
irrigation networks, can be formulated as a multi-objective optimization problem. In this …
